Citrus essential oils as biologically active substances in the human health preventive care

The work is devoted to the comparative analysis of the component composition of the essential oil of some species of the genus Citrus of different origin. Essential oil was extracted from the peel of kumquat (Citrus japonica Thunb.), lime (Citrus aurantifolia (Christm.) Swingle), and limequat (Citrus x floridana (J.W. Ingram & H.E. Moore) Mabb.) fruits by steam distillation using a modified Ginzberg receiver. The component composition of the essential oil has been established by the GC-MS method. In the studied species of the genus Citrus, the content of the main component of limonene varies from 50 to 95%. Differences are observed in the quantitative ratio of some components that relate to terpene hydrocarbons, alcohols, and their esters
